Hydrodynamics Of Swimming Microorganisms In Complex Fluids, Gaojin Li

Open Access Dissertations

Swimming motion of microorganisms, such as spermatozoa, plankton, algae and bacteria, etc., ubiquitously occurs in nature. It affects many biological processes, including reproduction, infection and the marine life ecosystem. The hydrodynamic effects are important in microorganism swimming, their nutrient uptake, fertilization, collective motions and formation of colonies. In nature, microorganisms have evolved to use various fascinating ways for locomotion and transport. Different designs are also developed for the locomotion of artificial nano- and microswimmers. In this study, we use several different computational models to investigate the behavior of microswimmers.

Microorganisms typically swim in the low Reynolds number regime, where inertia …

Poetry Matters: Radical Politics In Postmodern American Poetry, Christopher J. Padgett

Open Access Dissertations

Directly or indirectly, poetry produced in the postmodern era is implicated in the politics of the time. Postmodern American poetry, then, is not reducible to a single poetic mode or to a specific set of stylistic features. In other words, a more comprehensive understanding of postmodern American poetry can be made by employing a flexible version of Raymond Williams’ notion of uneven development, a theory that insists on the synchronic existence of dominant, residual, and emergent cultural elements. As the stylistically and politically diverse work of the six poets—Susan Howe, Robert Grenier, Gary Snyder, A.R. Ammons, Sherman Alexie, and Kenneth …

Laser-Processed Parchment Paper For Fabrication Of Chronic Wound Dressings With Selective Oxygenation, Manuel Ochoa

Open Access Dissertations

Chronic non-healing wounds (e.g., diabetic foot ulcers and bed sores) impact over 6.5 million Americans per year, costs in excess of $25 billion to treat on an annual basis, and are on the rise due to increasing levels of obesity and diabetes compounded by an aging population. A major inhibitor of healing is suboptimal oxygenation of the wound bed. Unlike acute injuries that receive sufficient oxygen via a functional blood vessel network, chronic wounds often suffer from the lack of a proper vascular network; thus being incapable of providing sufficient oxygen for tissue growth. Typical medical treatment of hypoxic chronic …

Investigating The Effects Of Ph On Alphaviral E3-E2 Glycoprotein Association, Organization, And Cellular Tropism, Jason Michael Sequra

Open Access Dissertations

In alphaviruses the role of E3 is required in protecting the fusion peptide region of E1 during intracellular transport. Throughout viral processing, the association of E2 and E3 is required for the successful trafficking and incorporation of E1 into the mature virion. This E3-E2 association has been observed to extend to mature virions in the solved structure for the envelope of Semliki Forest virus (SFV) and supported by the solved structure for the entire Venezuelan equine encephalitis virion (VEEV) with exclusive contacts being made between E3-E2. Immunization with monoclonal antibodies against VEEV E3 provided protection for mice challenged by lethal …

Dynamic Holography In Semiconductors And Biomedical Optics, Hao Sun

Open Access Dissertations

Three-dimensional scanning and display are rapidly-advancing new technologies with important commercial drivers such as 3D printing and remote imaging for big data applications. Holography is a natural approach to recording and displaying three-dimensional information because it uses phase-sensitive interferometry to record interference patterns when a reference beam encounters coherent light arriving from an object. The 3D information is contained in the values of wave optics. Holography is a broad field that goes beyond recording and displaying. For instance, holographic optical elements, which take advantage of holographic imaging principles, perform the functions of lenses, gratings or mirrors. Holographic interferometry is also …

On The Use Of Mechanical And Acoustical Excitations For Selective Heat Generation In Polymer-Bonded Energetic Materials, Daniel C. Woods

Open Access Dissertations

To address security issues in both military and civilian settings, there is a pressing need for improved explosives detection technologies suitable for trace vapor detection. In light of the strong dependence of vapor pressure on temperature, trace vapor detection capabilities may be enhanced by selectively heating target materials by external excitation. Moreover, polymer-bonded energetic materials may be particularly susceptible to heating by mechanical or acoustical excitation, due to the high levels of damping and low thermal conductivities of most polymers. In this work, the thermomechanical response of polymer-based energetic composites and methods for acoustical excitation are investigated in order to …

Metabolic Syndrome Screening In Seriously Mentally Ill Patients: A Quality Improvement Project, Annabel Moreno

Student Projects for Graduate Degrees

Seriously mentally ill patients who are taking second-generation antipsychotics have a high risk of metabolic complications, including obesity, diabetes mellitus type II, hypertension, and hyperlipidemia. Guidelines to screen for metabolic syndrome were established by the American Diabetes Association, American Psychiatric Association, American Association of Clinical Endocrinologists, and North American Association for the Study of Obesity (Clark, 2004). Compliance with implementing the guidelines to screen and monitor for metabolic syndrome vary from regular monitoring to little or none. This quality improvement project provided an educational intervention on screening and monitoring for metabolic syndrome in patients who were seriously mentally ill. The …

Looking Backward, Looking Forward: The Long, Torturous Struggle With Mosquitoes, Gordon M. Patterson

Arts and Communication Faculty Publications

The American anti-mosquito movement grew out of the discovery of the role of mosquitoes in transferring pathogens and public concern about pest and nuisance mosquitoes in the late 1800s. In the 20th century, organized mosquito control in the United States passed through three eras: mechanical, chemical, and integrated mosquito control. Mosquito control in the 21st century faces the challenge of emerging pathogens, invasive mosquito species, and balancing concerns about the environment with effective control strategies.

Drone Zoning, Troy A. Rule

North Carolina Law Review

The growing popularity of small civilian drones has generated a wide array of complex and unprecedented regulatory challenges. Many of these challenges, such as keeping drones away from manned aircraft, are matters that the Federal Aviation Administration (“FAA”) is clearly authorized and well equipped to address. However, several other drone policy challenges relate solely to drones’ potential to disrupt landowners’ privacy and to otherwise interfere with activities on the ground. The nature and severity of these conflicts often varies greatly depending on a drone’s specific location; drone uses that are welcomed in some city neighborhoods may be prohibitively disruptive in …

Surveillance Policy Making By Procurement, Catherine Crump

Washington Law Review

In Seattle, the police obtained a surveillance drone with the approval of a city council that did not realize what it was doing. In Oakland, following a council review that lasted literally two minutes, the city created a data integration center that networked together all of its existing surveillance infrastructure. In San Diego, elected representatives were only dimly aware that the law enforcement agency they supervised had built and deployed innovative facial recognition technology. In an age of heightened concern about the militarization of local police and surveillance technology, how do local law enforcement agencies obtain cutting edge and potentially …
